Siblings Kaylie and Tim Russell are haunted by the tragic events of their childhood, which culminated in the violent deaths of their parents. Convinced that an antique mirror, known as the Lasser Glass, is responsible for the systematic destruction of their family, an adult Kaylie orchestrates a meticulous plan to prove its malevolence. She secures the mirror, transporting it to their former
childhood home, and rigs the room with high-tech surveillance equipment, temperature sensors, and a weighted anchor mechanism designed to decapitate the entity if it attempts to manipulate them. Tim, having undergone years of psychiatric treatment to frame the past as a delusional trauma, is skeptical but agrees to participate, hoping to help his sister find closure.As the night progresses, the mirror begins to assert its influence, blurring the lines between reality and
hallucination. The glass exerts a supernatural tether, feeding the siblings false memories and visual distortions that make it impossible to distinguish between the current night and the traumatic events of their youth. Kaylie struggles to maintain her composure as the mirror mimics her mother’s descent into insanity, while Tim finds his rational worldview crumbling under the weight of impossible occurrences. The entity within the glass thrives on their confusion, feeding off their mounting terror and desperation.The tension reaches a breaking point when the siblings realize they have been trapped in a temporal loop, unable to escape the room. Every attempt to leave or destroy the mirror is countered by the glass’s ability to manipulate their perception of space and time. Kaylie’s scientific preparations prove futile against an ancient, hungry force that has claimed countless victims before them. In a harrowing climax, the mirror tricks Tim into triggering the weighted anchor, leading to a fatal mistake that mirrors the very tragedy they sought to rectify. As the anchor swings, Kaylie is caught in the path, meeting a gruesome end that solidifies the mirror’s victory. Tim is left alone, broken and framed for his sister’s death, as the Lasser Glass remains pristine and hungry, waiting for its next set of victims to fall prey to its infinite, malevolent gaze.
